As shown in these drawings, the cargo handling apparatus of the embodiment is installed in a ship 10, and is installed in an opening portion of a cargo room 12 that is formed in the ship 10 and in which a powdered material such as gravel is put. In this embodiment, the traveling hydraulic excavator 20 is mounted so as to travel in the front-rear direction of the ship 10 across the luggage compartment opening 14.

The traveling hydraulic excavator 20 has a traveling carriage 24 provided with traveling devices 22 on both sides.
Is a bridge type carriage structure having a width dimension that straddles the luggage compartment opening 14. At the center of such a traveling carriage 24 is mounted a device body 26 which is swivelable via a swivel mechanism and which mounts various drive sources. A swing excavator type excavator work machine 28 is attached to the body 26. In addition, a driver's cab 30 for the operator is provided.
The traveling device 22 is configured to have a drive sprocket 34, an idler 36, and a lower wheel 38 provided on the track frame 32, and the crawler belts 40 to be originally wound around them are provided on both sides of the luggage compartment opening 14. The hydraulic excavator 20 is configured to be deployed and laid in advance, and the hydraulic excavator 20 is allowed to travel along the crawler belt 40 on the deck of the ship.

In the excavator work machine 28, a multi-joint arm 41 consisting of a boom 41A and an arm 41B pivotally attached to the main body 26 is attached, and a bucket 42 is attached to the tip of the arm 41B to raise and lower the multi-joint arm 41. By driving, the bucket 42 can be operated to any position in the vertical direction so that cargo handling work can be performed.
As a result, the hydraulic excavator 20 operates the multi-joint arm 41 and the bucket 42 by the operation of the operator in the operator's cab 30 formed in the device body 26, and the granular material in the luggage compartment 12 within the swing operation range of the device body 26. It is possible to unload cargo. Then, with respect to a wide range of luggage compartments 12, the hydraulic excavator 20 is moved on the crawler belt 40 along the front-rear direction of the hull to change the cargo handling position, so that the shovel cargo handling of the entire area of the cargo compartment 12 is enabled. It

By the way, it is necessary to convey the powdered or granular material loaded by the hydraulic excavator 20 to the land side.
A transport conveyor 44 is installed on one side of the deck of the ship 10. This is a normal belt conveyor, the luggage compartment 1
It is installed longer than the length of 2 and extends to the bow side so that it can be supplied to the transportation equipment on the land side. The traveling carriage 2 of the hydraulic excavator 20 is provided in order to transfer cargo handling soil and the like by the hydraulic excavator 20 onto the transport conveyor 44.
4, in particular, a hopper 46 is attached so as to project from the outer surface of the track frame 32. The hopper 46 is set so as to move together with the hydraulic excavator 20, and the discharge port 47 thereof moves along the traveling center line of the transport conveyor 44. Therefore, by the hydraulic excavator 20, the luggage compartment 1
The earth and sand piled up from No. 2 are dropped on the hopper 46, and are discharged from the hopper 46 to the conveyor 44 to be carried out.

According to such an embodiment, the ship compartment 12
The traveling type hydraulic excavator 20 having the traveling carriage 24 having a length that straddles the opening 14 of the vehicle can be moved along the crawler belt 40 laid on the side deck of the luggage compartment 12 to move the position, and the center of the carriage can be turned. By operating the shovel work machine 28 provided in the main body 26, the shovel can be unloaded. Therefore, since the backhoe type unloading equipment by the hydraulic excavator 20 is mounted on the ship 10, unlike the conventional crane type unloading apparatus, the bucket 42 can be operated and moved to the position intended by the operator. Further, even the powder and granular material that has been compacted by transportation is hydraulically driven to generate a large excavating force, and a large amount of cargo can be handled. Moreover,
Since the reliable movement operation by the multi-joint arm 41 is possible, even if the ship 10 shakes or the like, the bucket 42
Does not cause an unexpected operation, there is no risk of the shovel 42 colliding with the wall surface of the luggage compartment 12, and a damage accident that accompanies the unloading of the ship 10 does not occur. Further, in the work on the ship 10, the excavator work machine 28 to the hopper 46
Since the powder and granules are not spilled during transportation, the unloading work can be performed with high work efficiency. In particular,
Since the hopper 46 is attached to the traveling carriage 24, the payout position from the bucket 42 is constant and the work can be continued in the same work posture, so that the work efficiency is high.

In particular, in this embodiment, the crawler belt 40 is used as a hydraulic excavator device wound around the traveling device 22 for loading on the ground, and when loading and unloading the vessel, the loading chamber 12 is placed on the vessel 10. The crawler belt 40 can be mounted so as to straddle it, and the crawler belt 40 can be detached here and deployed on the deck, and the crawler belt 40 that lacks can be appropriately added, and the crawler belt 40 can be moved along the deployed and laid crawler belt 40. For this reason, the hydraulic excavator 20 can be detached when the ship 10 travels, and can be used as a device that is mounted only during cargo handling, resulting in extremely high utilization efficiency.

If the traveling hydraulic excavator 20 has a structure in which the traveling carriage 24 is sized so as to straddle the luggage compartment 12, the existing traveling hydraulic excavator 20 can be used as it is. The unloading work from the carrier can be efficiently performed.

Next, FIGS. 4 to 5 show a second embodiment. In the first embodiment, the traveling hydraulic excavator 20 has the luggage compartment opening 14

That is, the bridge 50 is installed so as to cross the center of the luggage compartment opening 14 of the ship 10, and the traveling hydraulic excavator 20 with the crawler belt 40 removed can be moved on the bridge 50. The crawler belt 40 for running the hydraulic excavator 20 is laid in advance on the bridge 50, or the hydraulic excavator 20 with the crawler belt is mounted on the bridge 50 and at the same time the crawler belt 40 is removed and laid. The hydraulic excavator 20 travels on the laid crawler belt 40.

Here, in the second embodiment, the hydraulic excavator 2
When 0 travels along the longitudinal direction of the bridge 50, there is a high possibility that the rolling motion of the hull will affect the vehicle and cause abnormal travel.
Therefore, the traveling device 22 of the hydraulic excavator 20 according to the second embodiment.
Then, as shown in FIG. 6, the idler 36 is replaced with sprockets 34 at both ends, and the four sprockets 34 are engaged with the shoes of the crawler belt 40 to prevent slipping due to the inclination of the hull. Further, as shown in FIG. 6, a plurality of laterally projecting flanges 52 are provided on the outer surface of the track frame 32 of the hydraulic excavator 20, and in accordance with this, the flanges 52 are formed on the side edge portions of the bridge 50. The presser bracket that extends to the upper part of is attached along the traveling path. As a result, the one traveling device 22 side of the hydraulic excavator 20 is prevented from being lifted up due to the pitching swing of the ship 10 and is prevented from falling. The other configurations similar to those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

According to the second embodiment as described above, it is particularly effective when the width dimension of the luggage compartment 12 of the ship 10 is large. The crawler belt 40 is laid on the bridge 50, and the traveling hydraulic excavator 20 has the sprockets 34 at both ends. It is possible to move by the traveling device 22 having the above, and as shown in FIG. 7, when the hull leans to the left or right due to shaking, it is possible to prevent slipping or falling. Particularly, in the second embodiment, a normal hydraulic excavator device can be used as compared with the first embodiment, so that cargo handling can be performed by using the existing device. Further, as compared with the case of the first embodiment, the swivel position of the swivel device main body 26 is located in the luggage compartment 1.
Since it can move in the width direction of 2, the effective range of excavation is expanded,
Work efficiency increases. In addition, the traveling hydraulic excavator 20
May be normally placed on land and mounted on the ship 10 during the unloading work, and by doing so, the weight of the ship 10 can be reduced.

In the second embodiment, the bridge 50 has a fixed installation structure, but it may have a moving bridge structure that can move along the opening of the luggage compartment 12.
By doing so, it is possible to carry out the unloading work with the small shovel even when the cargo room range is wide.

[0023]

As described above, according to the ship handling method and apparatus according to the present invention, the crawler belt is laid on the bridge that crosses the side of the cargo room and the opening of the cargo room, and the crawler track is made to run on the track. Since the traveling type hydraulic excavator from which the car has been removed is run, it is possible to easily mount the hydraulic excavator on a ship and load the excavator without laying a special running path without forming a special running path. Therefore, the unloading work can be efficiently performed.
